258086 divided by 412 
The aim is to understand the frequency of 412 in 258086.

Advancing to step 1:
412 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 412

Let's proceed to step 2:
The number 412 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 412

Moving on to step 3:
If we divide 258 by 412, we get 0 and a remainder of 258.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 258 and we're left with 258.
Fetch the next digit (0) from the dividend, attach it to 258 and continue: 2580 / 412

Advancing to step 4:
The number 412 fits into 2580 6 times, leaving a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 2472 from 2580 leaves us with 108.
Take the next digit (8) from the dividend and append it to 108, then repeat: 1088 / 412

Let's proceed to step 5:
412 can be fit into 1088 2 times, resulting in a remainder of 264.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 824 from 1088 leaves us with 264.
Grab the next digit (6) from the dividend, add it to 264, then carry on: 2646 / 412

Step 6:
When dividing 2646 by 412, we get 6 with a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 626.0
Subtract 2472 from 2646 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 7:
1740 divided by 412 is 4 with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 626.4
The remainder is 92 after subtracting 1648 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 8:
412 can be fit into 920 2 times, resulting in a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 626.42
Subtracting 824 from 920 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
The number 412 fits into 960 2 times, leaving a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 626.422
If we subtract 824 from 960, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 626.422 and a remainder of 0.0136.
